Synthetic signals obtained by P-CORONA, for the radiation emitted by both the CBP and model PSI2 (see text), representative of the surrounding coronal material along the line of sight. Left, central, and right columns show the quantities $\overline{I}$, $\overline{|V|}/\overline{I}$, and P_L, respectively. From top to bottom, the rows correspond to the quantities obtained from the synthesis for the Fe10747, Fe5303, Si14301, and Si39343 lines, respectively.
